I am talking about a movie called "No Smoking".
It seldom happens that, each time you watch movie, you end up with different conclusions in the end.
It seldom happens that, each time you find some new detail, that you haven't noticed last time.
It seldom happens that, you can quote a movie as "A Riddle".
Based on an very abstract story Quitter's Inc. written by Stephen King, No Smoking takes that story to another level of abstraction.
